To all whom it magico/neem: 'Be it known that LROBERT E. "FRAME, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain 'new and useful improvement in Car Underframes, of which the following is a full, clear, description, such as wil. enable others skilled in the art to which it appertairis 'to malte and use the same, reference being had to the accompanying drawings, part of this s ecification, in which- Figure 1 is a top p an View of a car under frame constructed in accordance with my invention; Fig. 2 is a side elevation .of the parts shown in Fig. 1; andllig. 3 is a cross section al View taken on the line 3*-3 of Fig. 2. This invention relates` to car underframes, and has for its obiect to provide an underframe that is strong and which can be manufactured ata low cost. Referring to the drawings which illustrate the preferred form of my invention, 1 designates plates that form the webs of the center sills, and 2 designates commercially rolled members, preferably angles, that are secured to the upper and lower edge portions of said lates to form built-up center sills of cham nel-sh ape in cross section, the horizontal legs of said angles projecting outwardly andthe vertical legs of the anglesbeing ksecured to the outside faces of the plates 1. The draft pressed metal members 3 thatare secured to the ends of the center sills which project beyond thev bolster of the, underframes, the outer ends of connected to the channel-shaped end sill preferably by means .ofi angles 5 although the draft4 sills could be rovided with integral flanges for securing t ern,v to the end sill without departing from the spirit of my invention. Y,

As shown in llig. 2 the draft sills 3 are of greater depth than the end sills and their outer ends are reduced so that the flanges 3a thereon will lie between thel inwardly projecting-flanges of the end sill, the top iianges of thedraft sills being. vflush with" the top iiange of the end'sill. The inner, end-portions of the draft sills .are preferably. tele scoped-over the projecting end portions of the center sills and the vertical webs of said sills are secured together by rivets 6, the laterally projecting flanges of the draft sills and center sills also being securedv together by rivets 7 so that a very strong and rigid top -draft sills; substantiallyas described.

structure is produced. Preferably, the rivets 8 which secure the angles 2 to the web plates 1 at the end portions of the center sills also pass through the webs of the draft sills 3, and theupper and lower edges of the vertically disposed web plates of the center sills extend flush with the horizontal legs of the angles 2 secured to said plates so as to butt against the flanges of the draft sills, as shown in Fig. 3, thereby producing an exceptionally strong connection between the center sills and draft sills ,as all of the parts are closely ,nested together. f

The center sills are-separated at the bolster by flanged diaphragme 9 arranged back to back, as shown in dotted lines in Fig. 1,

and interposed between the center sills, and

the bolster is made upof web plates 10 which project laterally frein the center sills, said web plates having laterally projecting, commercially rolled members, preferably angles 1i, secured to the upper and lower edge. portions thereof to form an l-shaped structure, These laterally projecting lshaped members are secured'to the center sills bypairs of vertically disposed angles 12 and the end flanges 9a of the diaphragms be; tween the center sills are secured to said sills by the same rivets 13 which secure the connecting angles 12 to The bolster is provided with the usual transversely exten ing top and bottom cover plates' 14 which are secured to thexflanges of the center sills and to the flanges of the ll-sliaped membersthat project laterally from the ,center sills.

Having thus l claim as new and desire to secure by Letters atent is:

1. A car underframe comprising built-up center sills of channelesha e In cross section, and pressed metal channe shaped draft sills embracingthe end portions of the center sills and secured 'to the webs and tothe top and bottom llanges thereof; substantially as described. f l l 2. A car underframe comprising builtfup `center sills of channel-shape in cross section .arranged withv their flanges pro'ecting outwardly, pressed metal channel-s aped draft sills telesco ed center sills eyond the bolster, ,and fastening devices passing through the webs and the and bottom flanges ofthe center sills and the center sills.

over the end vportions of the 3. -A car underframe comprising a bolster, center sills projecting beyond the bolster and each consisting of a vertically dispose'd web plate having angles secured to the upper and ower edge portions thereof to produce a' channelshaped structure, pressed metal draft sills of channel-shape in cross section telescoped over the end portions of the center sills, and fastening devlces passing through the webs and the top and bottom'ianges of the center sills and draft sills; substantially as described.

' 4. A car underframe comprising a bolster, center sills projecting beyond the bolster and each consisting of a vertically disposed web plate and angles secured to the upper and lower edge portions thereof .and arranged with their flanges projecting outwardly, channel-shaped pressed metal draft sills telescoped over the end portions of the center sills, and fastening devices passing 'through the webs and the top and bottom flanges of the draft sills and center sills substantially as described. v

5, A car underframe comprising a bolster, channel-shaped center sills projecting beyond the bolster; and'each conslstingof a vertically' disposed web plate having angles secured to the outside faces thereof, the upper and lower edges of said plate extending flush withthe horizontal legs of said angles, and pressed metal channelshaped draft sills telescoped over the end portions of the center sills and secured to the webs and to the top and bottom flanges thereof; substantially as described.

6. A car underframe provided with a longitudinally extending channel-shaped sill .which :plate having commercially rolled members consists lof a vertically disposed web secured to the upper and lower edge portions thereof, a pressed metal extension conforming in cross section to the longitudinally extending sill and being in telescopic engagement with the end portion thereof, and means for' securing the webs and the top and bottom flanges of said members together; substantially' as described.

car underframe comprising flan ed pair of pressed metal iaback to back and arranged between said center sills, I-shaped members projecting laterally from the center sills, each of said members consisting of a vertically disposed web plate having angles secured to p securing -it between the flanges of the end erase? the upper and lower edge portions thereofl l an jecting in op osite directions, and means for said) members to the center sills; substantially as described. i

car underframe comprising center sills, each of which consists of a vertically disposed web plate haying angles secured to the outside faces of the upper and lower.l edge portions thereof, the horizontal legs of said angles projecting outwardly, a spacing member arranged between. the center sills, I- shaped members projecting laterally, from the center sills and each consisting of a vertically disposed web plate having a pair of angles secured to the up er and lower edge portions thereof, vertical y disposed angles connected to the top and bottom angles of the arranged with. their horizontal legs proi center' sills and to the top and bottom angles of said E-shaped members for securing said parts together, and top and bottom cover plates extending transversely over the center'. sills' and the I-sha ed members which project laterally there scribed.

9. A car underframe comprising a channelshaped end sill, a bolster, built-up center sills'of channel-sha e incross section which project beyond the olster,l and pressed metal channel-shaped draft sills telescoped over the end ortions of the center sills and connected to t e top and bottom flanges thereof, said draft sills having their outer ends reduced to sill; substantially as described.y 10. A car underframe provided with a longitudinal sill which consists of a vertically disposed web plate, angles secured tothe upper and lower edge portions of said plate and arranged with their horizontal flanges projecting laterally therefrom, and a pressed metal channel-shaped extension telescoped over the end portion of said sill and having its web secured to the vertical web platethereof and its top and bottom lianges secured Vto the angles at the upper and lower edges of said plate; substantially as described.
